SPECIFICATION forming part of Letters Patent No. 465,533, dated December 22, 1891.
Application filed December 19, 1890. Serial No. 375,244. (No model.)
To @ZZ whom t may concern.'
Be it known that I, WALLACE A. MORSE, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in a Combined Steam-Boiler and IVater Heater and Filter, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
This invention relates to the combination of a steam-boiler and water heater and filter having the novel construction hereinafter described, and set forth in the claims.
Figure I is an axial section of the apparatus in its 'more simple form, the section being taken on the plane of the fire-door. Fig. II is a horizontal section at II Il, Fig. I. Fig. III'is a vertical section of a spray-nozzle. Fig. IV is an enlarged detail horizontal section taken at IV IV, Fig. I. Fig. V is an enlarged detail vertical section showing the iillingring which is interposed between the headsheet of the Water-drum and the expanded end of the tube. Fig. VI is an elevation of the boiler, nbc., showing the water walls or jacket in vertical section. Fig. VII is a side View of a solid stay-bolt. Fig. VIII is an axial section of a tubular stay-bolt, both being shown in position; and Fig. IX is a View similar to Fig. VI, the interior structure being shown in vertical section, as in Fig. I.
The apparatus will'rst be described as shown in Figs. I to V.
1 is the mud-chamber, which is shown as made of heavy cast-iron and integral with the base-plate 2. The upper edge ofthe chamberl tits within or without the lower edge 3 of the vertical water-cylinder 4 of the boiler, and is secured thereto by rivets. The cylinder 4 has a bottom 5, which forms the top of the mud-chamber and closes the communication between the mudchamber and cylinder 4 at that place.. Said chamber and cylinder have communication, however, by pipes 6, having in them unioncouplings 7. The ends S of the pipes within the mudchambers are curved upward, so as to take the water from the upper part of the mudchamber, and the ends 9 of the pipes within the cylinder 4 are bent downward, so as to discharge the water in a downward direction into the bottom of the cylinder 4. The cylinder ends at top in a steam-dome 10, from which the steam escapes by a steam-pipe 11. At the bottom of the steam-dome is an annular plate 12, having a downturned flange 13, surrounding the central orifice 14. The pur- 'pose of the ange 13 is to prevent the water being carried up with the steam into the steam-dome. Any water adhering to the under side of the sheet or plate 12 by capillary attraction and moving toward the orifice .14.
would be broken by the downturned flange 18 and would drip from its edge. pit 15 surrounds the mudchamber.
16 is the `ash-door. 17 are the grate-bars.
The dre-chamber 18 surrounds the lower part of the water-cylinder 4.
10 is the lower annular water-drum, whose lower sheet 20 forms the top of the fire-chamber. The drum 19 is riveted to the cylinder 4 at the inner edges of the lower sheet 2O and tube-sheet 2l. The interiors of the cylinder 4 and drum 19 communicate by ports'22 and 22, made in the sides of the cylinder. The ports 22a are much larger than the ports 22 in order that they may be used as man-holes togive access from t-he cylinder 4 to the drums 19 and 27 for purposes ot' cleaning and repairs.
23 is an annular deiiector bolted at the upper edge to the cylinder above the holes 22, having a tight connection therewith at that point, but lbeing open all around the bottom edge 24, which is in proximity to the bottom of the cylinder, so that the water will be taken from that point to su pply the upward current of water between the detlector 23 and the wall of the cylinder. This upward current will be rapid, owing to great heat of this part of the cylinder, which is in direct contact with the lire.
25 are vertical water-tubes whose ends are expanded in the tube-holes of the tube-sheet 2O and in a similar sheet 26, forming the bottom sheet of the upper annular water-drum 27, whose connection and communication with the cylinder 4 are similar to the lower drum 19, the same referencenumbers being used. Through the tubes 25 the water ascends from the lower drum 19 to the upper drum 27. The tube- sheets 21 and 26 are not horizontal, but are inclined, as shown, the sheet 2O sloping downward from the cylinder 4 and the sheet The ash- ICO 26 upward from the cylinder. This is for the purpose of more easily removing or replacing the tubes should occasion demand it, as well as tofavor the passage of the products of combustion as they pass first inward and then outward among the tubes 25.
In order to j insure the circulation of the products of combustion among the tubes 25, the surrounding furnace-walls 28 are in contact with the outer series of the tubes, as seen at 29, so that the said current is forced to follow the line indicated by the feathered arrows in Fig. I, passing from the fire-chamber around the periphery of thelower drum, then first inward and then outward among the tubes 25, then around the periphery of the upper drum and what I term the econo- Inizer above it, and so to the chimney or smoke-flue 30. The economizer 31 is an annular chamber set directly on the top sheet Ot' the upper drum 27 and surrounding the steam-dome.
32 and 33 are man-hole extensions which extend outwardly from the economizer, traversng the inclosing wall or casing 28 and fitted with man-heads 34. The extension 32 gives means of access to the economizerchamber. The extension 33 contains the tilter 35, which extends horizontally across the extension and separates it into two chambers, the receiving-chamber 36 below and the dlscharging-chamber 37 above. The filter has perforate plates, between which is a^ny suitable filtering material. 38 is the water-supply pipe, leading from the pump and passing without opening through the mud-chamber and with atight joint through the plate 5.
The pipe-38 extends up near the center ofthe cylinder 4 to near its upper end, where it is bent outward and passes through the side of the cylinder into the drum 27, and then upwardly into the economizer through a tight joint in the `top of the drum and bottom of the economizer. The pipe carries at its upper end a spray device 3 9, of any suitable construction, through which the water is sprayed into the economizer. The spray is above the surface of the water, which surface 1s indicated by ybroken lines at 40. The water escapes from the economizer into the filter-extension 33, which extends into the body of the economizer at the inner end and 1s perforated at 4l for the passage of water from the economizer into the chamber 36. The water passes upwardly through the filter into the chamber 37 and escapes through a pipe 42, which extends downwardly through the bottom of the economizer and top of the drum 27 with a tight joint, and through the wall of the cylinder 4 into the cylinder, and
- downwardly through the central part of the cy1inder, and through the bottom 5 of the same into the mud-chamber 1,into which the lower end of the pipe discharges. The water, which has become heated in the pipes 38 and 42 and in the economizer, deposits its impurities in the mud-chamber 1, from which they are blown off through a pipe 43. The clear water passes through the pipes 6 into the cylinder 4, and, mixing with the descending water in the cylinder, Hows upward between the delector 23 and the side of the cylinder and through the holes 22 into the drum 19 and upward through the tubes 25 to the drum 27, from which it escapes through the holes 22 into the cylinder and is turned downward by the detlector 23 and descends within the cylinder to its bottom, as shown by the featherless arrows in Fig. I. The surface of the water in the drum 27 is indicated by broken line 44.
45 are water-gage glasses indicating the surface levels in the drum 27 and the economizer. The steam-spaces of the drum 27 and economizer 3l are in communication by pipes, one of which is shown at 46, Fig. I. These pipes extend in a circle entirely around the economizer. These pipes vinsure an equal steam-pressure in the econemizer and drum, and also bring the water in economizer up to same temperature as water in main part of boiler, thus helping to free it from impurities.
It has been said that the tube- sheets 21 and 26 are not horizontal and not parallel with each other, so that they will be oblique to the tubes 25, and in order to allow the easy introduction of the ends of the tubes into the holes 47 and the making of a tight joint I prefer to place a filling-ring 48 between the tube and the edge of the hole,'the ring being made Haring at both its outside and inside circumference to tit the beveled or countersunk edge of the hole and the iiaring end of the tube after it has been expanded. (See Figs. IV'and V.)
I am aware that the mattei' shown in these Figs. IV and V is old; but I have described the same so as to show the best manner of attaching these parts.
In the modification shown in Figs. VI and IX the construction and arrangement vis just the same as that already described, except-ing that a water wall or jacket 28n takes the place of the brick wall o1' casing 28, (shown in-Fig. I,) the water-wall vextending from the baseplate to about the top of the drum 27. The interior of the water-wall communicates with the lower part of the cylinder 4 by pipes 49 and with the interior of the drum 27 by pipes 50. There will be an upward movement of water in the water-wall.
51 are tubes extending through the interior of the water-wall from the fire-chamber 18 to the smoke-space above. These tubes pass through the annulaioifset-sheets 52, and their ends are expanded to make a tight joint therewith, as usual. The sides of the waterwall are stayed by bolts 53, which may be solid, as seen in Fig. VII, or tubular, as seen in Fig. VIII. In either case the ends are reduced to pass through holes in the sheets 54, leaving a shoulder bearing against the inner side of the sheet, the ends of the bolts being riveted on the outside.

IIO
An annular deliector is shownby broken lines at 29, Fig. Vl, said deflector extending all around from the water-wall to the outer annular series of tubes and performing the same ofce as the annular projections 29 of the brick casing-that is, deiiecting the ascending products of combustion inward, so as to cause them to circulate among the tubes 25. This deector may be dispensed with, if preferred.
It will be noticed that the cylinder 4 extends from the mud-chamber to the economizer and is iirmly secured to them and to the drums 19 and 27, so that there is no possibility of the parts getting out of theirrelative positions, and also that the base-plate, ywhen t made integral with the mud-chamber, will give great stability to the whole apparatus.
